This part of ISO 6145 specifies a method for the preparation of calibration gas mixtures by usingelectrochemical generation of a calibration component and introduction into a complementary gas flow. Byalteration of the gas flow or the charge passed through the cell electrolyte, it is possible to change thecomposition of the gas mixture. The relative expanded uncertainty of the calibration gas content, U, obtainedby multiplying the relative combined standard uncertainties by a coverage factor, k = 2, is not greater than 5 %.
